Description

A profiling grinding device suitable for underwater environment

technical field

The invention belongs to the field of underwater cleaning devices, and in particular relates to a profiling grinding device used in an underwater environment, which can clean small holes and recover sundries.

Background technique

Due to the erosion of various substances in the water, various facilities in the underwater environment are prone to attach certain sundries to the surface, especially the small pore structure, thus affecting the installation of various equipment or the sensing range of the sensor. At the same time, in order to ensure the quality of the underwater environment, many application fields need to recycle the cleaned up debris to avoid pollution to the water body. It is difficult to recycle the cleaned debris. When using, it is necessary to use corresponding grinding tools for holes of different sizes. Inaccurate positioning or wrong size judgment will often cause the rigid grinding head to remove the hole structure. Therefore, there is a need for underwater machining of a grinding mechanism that is less structurally destructive.

SUMMARY OF THE INVENTION

The invention provides a profiling grinding device suitable for underwater environment, so as to solve the problem that the hole structure is easy to be damaged when cleaning complex holes in the underwater environment at present.

The technical scheme adopted by the present invention is as follows: the bracket is fixedly connected to the chassis through screws, the drainage hole is fixed to the chassis, the sealing washer is fixedly connected to the upper part of the bellows, the lower part of the bellows is connected to the chassis, and the motor is connected to the chassis through the motor bracket , There is a sealing ring between the motor and the inflatable chamber. An inflatable pipe is installed on the cylindrical wall of the inflatable chamber. The other end of the inflatable pipe is pierced from the bottom of the chassis. Inside the inflatable chamber, one end of the connecting gas needle is fixedly connected to the motor output shaft , a rotating disk is fixedly connected in the middle section of the connecting air needle, the rotating disk is rotatably connected with the upper mouth of the inflatable chamber, and the airbag and the grinding net are fixedly connected above the rotating disk and the outside of the connecting air needle;

The upper connection port of the air needle is located in the air bag, and the lower connection port is located in the inflation chamber.

The advantage of the invention is that the structure is novel, and the flexible air bag and the grinding net are used as the grinding structure. The structure can expand the air bag and the grinding net to the required shape by inflating the air bag, and the shape can be changed at any time as the grinding progresses. It realizes the cleaning of complex holes and ensures the efficiency of grinding; by sealing the processing area, and using an electric pump to remove the impurities from the cleaning area together with the liquid, the liquid in the bellows is discharged through a drain port, and the liquid that falls off during cleaning is discharged. The impurities are discharged to ensure the cleanliness of the liquid and prevent it from polluting the environment.

Detailed ways

Referring to FIG. 1, the bracket 13 is fixedly connected to the chassis 7 by screws, the drain hole 6 is fixed to the chassis for connection with the electric pump, the sealing gasket 4 is fixedly connected to the top of the bellows 5, and the bottom of the bellows 5 is connected to the chassis 7, the motor 12 is connected to the chassis 7 through the motor bracket 13, and there is a sealing ring 11 between the motor 12 and the inflatable chamber 9 to prevent the gas from escaping from the connection between the two during inflation, causing the air pressure in the air bag 3 to be unstable, and the inflatable chamber 9 Inflatable pipeline 10 is installed on the cylindrical wall of the cylinder, and the other end of the inflatable pipeline 10 is pierced from the bottom of the chassis 7 to connect the air pump; referring to FIG. It is fixedly connected so that it can rotate together with the motor output shaft, and the rotating disk 8 is fixedly connected in the middle section of the connecting air needle 14, and the rotating disk 8 is rotatably connected with the upper port of the air chamber 9. The chamber escapes, the airbag 3 and the grinding net 2 are fixedly connected above the rotating disc 8 and the outside of the communicating gas needle 14, and the airbag 3, the grinding net 2 and the rotating disc 8 rotate synchronously with the communicating gas needle 14;

The upper connection port 141 of the communication needle 14 is located in the airbag 3 , and the lower connection port 142 is located in the inflatable chamber 9 , and is used for delivering gas from the inflatable chamber to the airbag 3 .

working principle

When in use, connect the air needle 14, the grinding net 2, and the air bag 3 into the hole of the workpiece 1 to be processed, and then inject air into the air chamber 9 through the inflation pipeline 10, and then connect the air needle 14 through the upper connecting interface 141. And the lower connection interface 142 transports the gas from the inflatable chamber to the air bag 3, the air bag drives the grinding net 2 to expand, so that the grinding net 2 is attached to the surface to be processed, at this time, the motor 12 is started, and the motor output shaft is connected with the connecting air needle 14. The ventilation needle 14 is also connected to the rotating disc 08, and the airbag 3 and the grinding net 2 are fixed on the rotating disc 8 and rotate together with the rotating disc 8, thereby completing the grinding process of the surface to be processed; the schematic diagrams of the inflation and contraction of the airbag are shown in Figures 3 and 4 ;

During the grinding process, in order to ensure that the debris will not escape into the water and avoid pollution to application sites with high water quality requirements, such as the spent fuel pool of a nuclear power plant, the present invention designs the liquid extraction step. The water suction port is connected to the drainage port 6 of the present invention, and along with the cleaning of the hole to be machined by the grinding net, the cleaned debris is drawn out together with the liquid in the bellows 5 at any time;

During processing, the sealing washer 4 abuts on the surface of the workpiece 1 to be processed to improve the pumping efficiency and prevent debris from being scattered in the water. At the same time, due to the elasticity of the bellows 5, the sealing washer 4 can be guaranteed to be in contact with the surface to be processed at all times;

After the processing is completed, the gas in the airbag 3 is discharged through the connecting gas needle 14, the inflation chamber 9, and the inflation pipeline 10. At this time, the airbag shrinks, and the workpiece 1 can be taken out to process the next hole.
